Due Date Uncertainty

So my doctor is trying to tell me that I am only 27 weeks along. Its a single pregnancy and I'm already the size I was with my first baby at 38-39 weeks along. She's dropped(I know because I can breathe again) and is grinding her head around in the pelvic area, and there is just no more room for her to move.
I am not sure how to bring my concerns about this to my doctor as she's mad at me for not starting prenatal care till what she says was 22 weeks. It's just I really feel its going to be sometime soon and I need advice on what to do about it?

Quoting NinjaBaby:“ So my doctor is trying to tell me that I am only 27 weeks along. Its a single pregnancy and I'm already ... [snip!] ... what she says was 22 weeks. It's just I really feel its going to be sometime soon and I need advice on what to do about it?”

Have they done an u/s to estimate how big she is?

My son droped at liek 30 weeks and went back up so they can move again. ANd just my two cents i would fuss at you two for waiting so long lol.

How did the doc come to their conclusion? External exam or ultrasound? If you really think you are farther along and the doc is being difficult I would try to get a second opinion.

Well the most recent due date (June 29th) was based on a superquick ultrasound. I just don't know. It's soooo frustrating but I had a problem pregnancy with my son so I hate the idea I might be going to the doctor and crying wolf and making a fool out of myself.

better to make a fool of your self and ease your worries then be all stressed about it.
